Starting issue
If my sign. doesn't show, this is a '99 7.3 ..
It seems like if I don't start it on a reg basis like every other day, it get's harder and harder to start. It was at the airport for 4 days while I was gone and it took a while and I had to push the pedal down once before it would start. Now today after 4 days of not starting it cranks good but won't fire up and it doesn't get that cold here in south Texas, 40 this morning.
Also, when I turn the ignition on I hear something running like an electric motor or something and I haven't noticed that before. Is that a concern or what ?
I've got the battery charger on the main battery now so I won't run it down. I've waited for the "wait to start" light to go off before cranking. Usually during the summer months I just jump in and start right up and it's good to go.
What could be causing this issue ? new fuel filter and oil filter and change just one month ago.
Any suggestions or help is appreciated ..
Thanks

Many things could cause this, glow plugs, glow plug relay, fuel, etc. Here lately we are seeing a lot of GPR symptoms. After your WTS light goes off and while you are cranking, do you notice a lot of white smoke coming out of your tailpipe?
Electric motor running is probably your fuel pump.
Look at all of the cold start threads in this section.

The batteries are both clean tight and making good contact.
I hate to seem ignorant but where is the GPR located and is it hard to replace ?
Is it like the CPS, where there are some better than others ?
Thanks, and btw I'm out in the country and can't just run to town ..

Check Battery (s)
Check GPR
Check Glo Plugs
You and alot of other people are having the same problem. It was not that cold here either but mine started having cold start issues. Turns out I had four bad Glo Plugs on the passenger side..
You also have a little compressor under the hood right side that buzzes for a while. It pumps up air to run your vacume controls on the heater.

There is also a YT video on how to test. Do you have white smoke coming from your exhaust while trying to start?

These are low compression diesels. If it's below 45 or so and your glow plugs aren't working, it may be hard to start. If it starts fine after being plugged in overnight, it's most likely a problem with something in the glow plug system. It never hurts to have the batteries load tested, too.

OK thanks for locating the GPR for me..
Are they all about the same or is one brand better than the other.
Also, I can't see any white smoke coming out my exhaust.
I'm going out and trying to start it again after the chargers been on it a while
and the sun is shining down hopefully to warm it up..

LMAO.. I went out got in and just turned it on and never waited for anything
just cranked it and it started right up like nothing was wrong.
It still concerns me about the GPR and if I should replace it .
Where can I get one other than the stealership ? and are they expensive ?

Get a multi meter and test your GPR (simple) with a volt test. Then check your Glo Plugs for Ohms with the meter. There are youtube videos that show you how to do it. You dont want to just replace the GPR without testing it. Plus once your truck as been started for the morning it will probably start easier after that first hard start because it is warmed up.

If you are not getting white smoke during your failed start attempts, the injectors may not be firing. While you are cranking, the FICM needs to see 10.5 volts in the system to fire the injectors. Have someone read the volts across the battery posts while you are cranking. If either battery is dropping below 10.5 volts, you have a battery issue.

And, the wait to start light has little to do with the glow plugs, actually. In colder temps, the glow plugs are on much longer than the wts lt. So, you may just want to wait...say a minute or so before trying to start when cold.
